I'm going to respray hood and install clearbra and I'm really confused the paint due to lack of curing time, some people says that 3 days ok or at least 90 days because when remove a clearbra it could be possible to lift off with paint. I'm going to European autobody in Toronto.

anyone experienced??

Every body shop will have different curing methods, so there's no absolute standard, but 30 days is more than sufficient.
